MIPS: Fix sched_getaffinity with MT FPAFF enabled

2015-10-13T02:46:01Z

commit 1d62d737555e1378eb62a8bba26644f7d97139d2 upstream. p->thread.user_cpus_allowed is zero-initialized and is only filled on the first sched_setaffinity call. To avoid adding overhead in the task initialization codepath, simply OR the returned mask in sched_getaffinity with p->cpus_allowed.

security: remove unused parameter from security_task_setscheduler()

2010-10-20T23:12:44Z

All security modules shouldn't change sched_param parameter of security_task_setscheduler(). This is not only meaningless, but also make a harmful result if caller pass a static variable. This patch remove policy and sched_param parameter from security_task_setscheduler() becuase none of security module is using it.

MIPS: Use set_cpus_allowed_ptr

From: Julia Lawall Use set_cpus_allowed_ptr rather than set_cpus_allowed. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @@ expression E1,E2; @@ - set_cpus_allowed(E1, cpumask_of_cpu(E2)) + set_cpus_allowed_ptr(E1, cpumask_of(E2)) @@ expression E; identifier I; @@ - set_cpus_allowed(E, I) + set_cpus_allowed_ptr(E, &I) // Signed-off-by: Julia Lawall To: peterz@infradead.org To: mingo@elte.hu To: tglx@linutronix.de To: oleg@redhat.com To: linux-mips@linux-mips.org To: linux-kernel@vger.kernel.org To: kernel-janitors@vger.kernel.org Patchwork: http://patchwork.linux-mips.org/patch/1087/ Signed-off-by: Ralf Baechle

CRED: Wrap task credential accesses in the MIPS arch

2008-11-13T23:38:37Z

Wrap access to task credentials so that they can be separated more easily from the task_struct during the introduction of COW creds. Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id(). Change some task->e?[ug]id to task_e?[ug]id(). In some places it makes more sense to use RCU directly rather than a convenient wrapper; these will be addressed by later patches.

[MIPS] Use find_task_by_vpid in system calls

2008-02-19T17:01:30Z

There are some places left in mips, that lookup task in initial namespace, while the code doing so gets the pid from the user space and thus must treat it as virtual. Signed-off-by: Pavel Emelyanov Cc: "Eric W. Biederman" Cc: Ralf Baechle Signed-off-by: Andrew Morton Signed-off-by: Ralf Baechle
